The EKI 1029 narrow-band bodypack receiver is an ideal choice for conference applications – with up to 32 switchable channels (EKI 1029 PLL 32), even very large conferences can be catered for. The EKI 1029 can easily be attached to a shirt or jacket pocket via the clip on the back – or the conference participant simply places the receiver on the table. The headphone socket allows connection of a wide range of headphones, for the extensive Sennheiser range see the chapter on “Accessories”. Models range from lightweight stethoset headphones to almost invisible earphones. Even the hearing impaired are catered for with the neck induction loop or induction couplers. For example, a headphone model such as the HD 1029 offers optimum comfor t even when worn for many hours.

The EKI 1029 is automatically switched on when you connect a headphone plug to the headphone output socket. When the plug is removed, the receiver is switched off again. If no IR signal is received, energy-saving circuitry switches the receiver – with headphones connected – to stand-by. This prevents the accupack from being discharged too early, and there is no need to disconnect the headphones during conference breaks. If the IR signal received is too weak for good reception, the EKI 1029 mutes the audio output signal via the built- in squelch.

The BA 1029 accupack is inserted at the side of the receiver. For recharging purposes, the entire receiver (with the accupack inserted) is inserted into a slot in the L 1029 charging and transport case, versions are available for 20 or 75 receivers. Since the receivers have an operating time of approx. 30 hrs, they do not require daily recharging.

The L 1029 transport and charging case serves to store, transport and recharge the EKI 1029 receivers. The L 1029-75 version is designed for 75 receivers and the L 1029-20 for 20 receivers. For recharging purposes, the receivers are inserted into the recharging slots (1), and the accupacks remain in the receivers. In addition, you can recharge up to five spare accupacks (2). The plug-in mains unit NT 29 is connected as shown in the drawing (3). It is not delivered with the case but must be ordered separately in the version you require (European, UK or USA versions available). The L 1029 is fitted with a test socket (4) to check the voltage of the accupacks while they remain in the receivers.
